1引言

近年来随着科技的飞速发展，单片机的应用正在不断地走向深入，同时带动传统控制检测技术日益更新。

遥控消防车，是无人员投入火灾现场必备的终端设备，是一种代替人员进入火灾现场灭火的设备。智能消防车系统主要由：STC89C52单片机，NRF24L01无线收发模块，左右减速电机，步进电机，水泵，风扇等部件组成。可进行远程控制灭火。

使用时，以STC89C52系列单片机为控制核心设计摇控系统的发射器与接收器。摇控器由单片机、六个按键和NRF24L01模块等组成.六个按键分别代表车的前进和后退、左转和右转、启动灭火风扇和启动二氧化碳。摇控器通过NRF24L01发射出去，接收器接收后，辨别发射传输的信息，对车发出命令进行灭火。
